SPECIFICATION forming part of Letters Patent No. 730,554, datedj'une 9, 1903.

Application filed December 6, 1901. f serial No. 84,976. on model.)

To all whom it may concern: i Be it known that I, JOHN MCBRIDE, Sn, a

citizen of the United States, residing at Phila-- delphia, Pennsylvania, have invented anew and useful Machine for Conveying,Trimm in g,

modities shipped in bulk-with the least;

amount of manuallabor; and my invention is specially applicable to the moving of cargoes of such commodities in the holds of vessels and in coal-yards and other storages.

To this end my invention consists of a framework upon wheels and means of moving and steering the same in combination with an ascending-chute and scrapers and endless chain or chains and sprocket-Wheels and-a motor to operate said chains; also, a construction and arrangement for folding the chute and framework and controlling and guiding the endless chains, so as to enable it to be lowered into the hold of a vessel and moved about therein to bring the cargo within convenient reach of the hoistingapparatus through the hatchway, and an arrangement of discharging spouts and gates fordirecting and controlling the course of the material-in different directions ,from the top of the ascending chute through chutes to various points as desired.

The construction and operation of my inven tion are hereinafter particularly described, and shown in the accompanying drawings, in

I arbor or shaft 9 is rotatable in either direc- Which Figure 1 shows a side elevation thereof. Fig. 2 is a vertical sectional view of thede- 3 Fig. 3 is a Vice in line, with the lifting-eye. rear view of. the device ;;Fig. 4, a sectional lengthwise elevation thereof; Fig. 5, an enlarged view of one of the scrapers and springs; Fig. 6, the clutching deyice for controlling the motion of the truck-hoisting device. Fig. 6 is a plan view of the scraper-strips and adjacent parts. Fig. 7 shows an inverted plan view of the truck and mechanism for steering the same. Fig. 8 shows in vertical section in the plane indicated by the dotted line 3 g on Fig. 2. Figs. 9 and 10 respectively show transverse and lengthwise sectional views of the chute, and Fig. 11 shows an enlarged sectional View of the clutch for engaging and disengaging the propelling-wheels of the truck from the motive power.

. Referring to the drawings, 1 represents a truck supported upon wheels 2 and 2 and axles 3 and 3. *Onthe rear axle 3 is fitted a wormwheel 4, which engages an endless screw 5 on an arborfi. On the arbor 6 is a worm-wheel 7, which is turned by an endless screw 8 on the arbor 9. The arbor 9 is fitted with a sprocketwheel 10, turning with a hollow shaft 9' a connected cupshaped member 11 of a friction-clutch 11, said hollow shaft 9 fitting upon and turning freely on thearbor 9 and engaged and disengagedas-to rotative motion with the arbor 9 bya clutch 11. Thesprocket= Wheel 10 is turned by an endless chain 12, driven by asprocket-wheel l? on the arbor 22 of amotor 14, suitably supported on the truck 1. 0n the arbor 9 is fitted a spurwheel 15, attached to and turning with the cup-shapedin'ember 16 of the friction-clutch 16, connected as to rotative motion with the arbor 9:by a clutch 16. The spur-wheel15 meshes with a spur-wheel 17 on a countershaft or arbor 18, provided with and turned by a sprocket-wheel 19, propelled by an end;

less chain 20, driven by a sprocket-wheel 21 on the arbor 22 of the motor 14.

Theclutches 11 and 16 maybe of any known form, but are preferably frictional, and are controlled bya connected lever 23, so that the tion, with a resulting progress of the wheels 4 and truck 1 in either directionyor by plac ing the lever 23 in intermediate position the having bearings 25, supporting an arbor 26, carrying sprocket-Wheels 27, which carry endless chains 28, that pass obliquely downward around sprocket-wheels 29 on an arbor 30, fitted to turn in bearings 31 in a frame 32, consisting of parallel links or bars attached by pivots 33 to the end of the truck 1. The frame 32 is held in extended position by links 34 and 35, pivotally connected together and to the frames 24 and 32, so that when straightened out the frame 32 is held in horizontal position, and when bent upward the frame 32 is raised in a vertical position, slacking the chains 28 and bringing the arbor 30 and sprocket-wheels 29 within the vertical plane of the end of the truck 1 and permitting the machine to be hoisted and lowered through hatchways otherwise too small to allow it to pass in extended position.

Below the under side of the endless chain 28 is placed a trough or chute 36, upwardly inclined from the plane upon which the wheels 2 and 2 rest, terminating in a hopper 37, having downwardly-inclined nozzles or spouts 38, 39, and 40, provided with gates 41, 42, and 43, through which material deposited in the hopper 37' can be discharged in either lateral direction or a forward direction through chutes which are preferably made telescopic.

Upon the chain 28 are attached hooked scrapers 47, pressed downwardly by springs 47, which scrapers propel the coal or other like commodity upward in the chute 36 and deliver it in the hopper 37. The scrapers 47 are preferably made of elastic material and are divided into strips 44, forming grapplehooks, so as to present narrow points to engage in the interstices between the lumps to be raised without being held out of engagement by any lump lying under the point of one scraper.

The lower end of the chute 36 is slit in strips 45, having pointed ends, so as to readily pass under the coal, the points being elastic, so as to apply closely to the floor or deck. The chute 36 is hinged at a point 48, so that it can be raised into vertical position within the vertical plane of the end of the truck 1 to permit the apparatus to be raised and lowered through the hatchways.

The arbor 26 is propelled by a gear-wheel 49, connected therewith and driven by a pinion 50 on an arbor 51, turning in bearings 52 in the frame 24 and receiving motion from a sprocket-wheel 53, connected by an endless chain-54 with a sprocket-wheel 55 on the arbor 22 of the motor 14. The sprocket-wheel 53 is connected as to rotative motion with the arbor 51 by a clutch 56, by means of which the motion of the elevating portion of the apparatus can he started or suspended.

The endless screw 5 is connected as to rotative motion with the arbor 6 by a clutch 58, so that the shaft or arbor 6 may rotate without rotating the screw 5, and upon the end of the arbor 6 is a winding-drum or winch 59, which may be used with a rope-tackle to hoist the apparatus by suspending it by the eye 60, formed in the top of the frame 24.

Having described my invention, what I claim is- 1. In a machine for conveying and moving commodities in bulk, a truck provided with means of propulsion 'in either direction, in combination with a framing and an inclined chute and bearing supported on said frame, and an arbor bearing sprocket-wheels and inclined endless chains provided with slit elas- 1 tie hooked scrapers arranged to raise commodities in said chute as and for the purpose set forth.
